Radiolytic synthesis and characterization of PVA and chitosan based conductive polymer membranes for alkaline fuel cells

Stoševski Ivan D. / Krstić Jelena I. / Vokić Nikola Č. / Kačarević-Popović Zorica M. / Miljanić Šćepan S.

Poly(vinyl alcohol) (PVA) and chitosan (CS) based polymer membranes for alkaline fuel cells were synthesized by gamma irradiation method. They were swollen with 6 M KOH solution and their ionic conductivity and gas permeance were investigated as a function of temperature. They show high ionic conductivities at room temperature, which wasn't reduced over a period of few months. No gas flow through membranes was detected at any temperature and pressure. These properties show that the membranes could be potentially applied in alkaline fuel cells.
